Description

Штукатурные растворы на основе горелопородных цементов, извести |и песка используютс  при П1р1оизвадст1ве штукатурных работ открытым способом в зимних услови х.Plastering solutions based on flame-forming cements, lime and sand are used in the construction of plastering works in an open way in winter conditions.

Известные цементно-известковые растворы дл  таких работ предусматривают введение в них хлорной извести, вызыва  этим значительный расход цемента.Known cement-lime mortars for such works involve the introduction of bleach into them, causing significant cement consumption.

Отличительна  особенность предлагаемого способа состоит в добавлении к воде затпорени  раствора су..чьфата натри  в 1 ол1;честве около 1% веса цемента.A distinctive feature of the proposed method is to add a sprinkling solution of sodium sulfate to 1 ol1 to water, which is about 1% by weight of cement.

Применение горелопородного цемента сокращает расход портландцемента , а применение су:п5фата натри , помимо ускорени  твердени , увеличивает морозостойкость и 1;рочность раствора после оттаивани .The use of flame-retardant cement reduces the consumption of Portland cement, and the use of soo: sodium sodium, in addition to accelerating hardening, increases frost resistance and 1; efficiency of the solution after thawing.

Горелопородный цемент представл ет собой продукт совместного иомола (до тонкости помола портланд-цемента) с.ледуюн нх компонентов: б8|| горелой породы, 30% портланд-цемента и 2% природпого гигса.Burnt-breed cement is a product of co-iomol (to the fineness of portland cement grinding) of the following components: b || burnt rock, 30% Portland cement, and 2% natural gas.

Прочность изготовленных образцов, выдержанных в течение 1-5 еуток прп температуре минус 19-25° и продолжающих твердеть после оттаивани  при температуре плюс 1 -15, а также образцов из этих же составов, выдержаиных в обь:чных услови х хранени , характеризуетс  след ю;цими данными:The strength of manufactured specimens that were aged for 1–5 months at a temperature of minus 19–25 ° and continued to solidify after thawing at a temperature of plus 1–15, as well as samples from the same compositions, kept in bulk storage conditions, are characterized by the following ; zimi data:

Как видно из таблицы, добавка сульфата натри  в количестве 1% к воде затворени  растворов действует значительно эффективнее, чем добавка хлористого кальци , и способствует быстрому повышению прочности образцов непосредственно после оттаивани .As can be seen from the table, the addition of sodium sulfate in the amount of 1% to the mixing water of the solutions acts much more efficiently than the addition of calcium chloride, and contributes to the rapid increase in the strength of the samples immediately after thawing.
